Title: Improvements in or relating to radar display apparatus
Inventor: PARKER ERIC
IPC: G01S7/04
Filed: 1963-01-25
Abstract: 1,004,756. Radar. DECCA Ltd. April 17, 1964 [Jan. 25, 1963], No. 3293/63. Heading H4D. In a mobile radar station a true motion display formed upon the long persistence screen of cathode-ray tube 10 is viewed through a semitransparent reflector 25 mounted so as to bisect the angle between the screen and a plotting member 16, which is carried upon window 15 in the top side 12 of a viewing hood, whereby a virtual image of the face of the plotting member appears superimposed upon the screen. The plotting member is connected by a parallel linkage to sleeve 22, slidable upon rod 19, and may be moved over the face of the window without rotation or may be lifted clear. It may consist of a rectangular sheet of glass or polymethyl methacrylate and be edge illuminated by lamps 30 through slit 32 (Fig. 3, not shown). Markings may be made upon its upper face by a pencil, the tip of which may be illuminated so that it is visible by reflection as it approaches the face or by pressure-sensitive adhesive paper as described in Specification 959,114. In use the trails of moving targets and the track of the radar station are marked in before resetting the display, when necessitated by movement of the radar station towards a boundary of the area displayed, and immediately thereafter the plotting table is moved so that the plotted information is superimposed optically upon the new positions of the targets. Alternatively, the plotting member may be movedso that one point on it appears to remain over the position of the station, whilst the tracks of the targets are plotted. In this way a relative motion plot is obtained from which any collision risk may be estimated. The semi-transparent reflector may comprise a sheet of circularly-polarizing material to prevent reflections, e.g., of viewers' faces, as described in Specification 898,770, and it may be arranged to be movably mounted so that it can be put out of the way when not required. The plotting member may bear a range and bearing graticule.

Title: Apparatus for use in loading film cassettes
IPC: G03B17/34
Filed: 1960-01-29
Abstract: 939,162. Loading cassettes. GEVAERT PHOTO-PRODUCTEN N.V. Jan. 29, 1960 .[Jan. 30, 1959], No. 3328/60. Class 98 (1). In apparatus for loading film into a hingedtype cassette, the cassette is supported inside a chamber, and means are provided within the chamber but manipulable from outside for opening and closing the hinged lid of the cassette, the chamber having an opening through which a film may be delivered into the cassette when the latter is open. The chamber is a light-tight box 1 having an opening 44 through which the film is delivered. This opening may be connected directly by a shoot 2 to a film-dispensing device 65 of the type described in Specification 939,161. One wall 6 of the box 1 is hinged at 7, and can be opened into the position shown in dotted lines (Fig. 9) by an arm 8 operated by a cam mechanism (Fig. 4, not shown). The cassette 51 is supported on this wall. The cassette has a hinged lid 55, which is locked closed by a slide 57 having projections 58 which engage in notches 59 on the cassette frame 53. The slide has two square holes 62 with dove-tailed edges. The cycle of operations is controlled by two long levers 30, 31, spring-biased to bear against rotating cams 18, 19 mounted on a shaft 11. As cams 18, 19 rotate, levers 30, 31 move towards or away from shaft 11. In addition to this displacement transverse to their length, the levers can also be given a longitudinal displacement by a further pair of cams 16, 17 mounted on the same shaft 11, and acting on a bell-crank lever 20 pivoted at 24, and pivotally connected to the lower ends of the levers at 28, 29. The levers carry cylinders 45, 45<SP>1</SP>, each cylinder having a central spring-loaded rod 46, 46<SP>1</SP>. The forward ends of rods 46, 46<SP>1</SP> have conical heads 48 (Fig. 7), which can enter into engagement with the edges of the holes 62. The cycle of operations commences with a cassette 51 laid in position on the opened wall 6 of the box 1, which is then closed. Levers 30, 31 move forwards towards the cassette, so that the conical heads 48 enter into the holes 62, and then slightly downwards, so that the heads engage under the bottom sloping edges of the holes (position of Fig. 7) and draw the slide 57 sufficiently downwards to unlatch the cassette lid. The levers then swing backwards, taking with them the lid, which thus hinges open (position of Fig. 9). A film is now allowed to fall through opening 44 into the cassette, after which the levers move forward once more to close the cassette lid, re-latch the slide 57, and then disengage the conical heads 48. The upper ends of the levers 30, 31 carry rollers 38, 39 which move a slide 42 thus uncovering opening 44 at the right moment to allow a film to fall into the opened cassette. The contours of the cams 16, 17, 18, 19 are so designed as to cause all these movements to occur, in the correct sequence. The whole cycle of movements may be controlled automatically by a suitable arrangement of mechanism (Fig. 12, not shown), and may take place in a lighted room.
